SINGLE AIR PRESSURE CONTROL SYSTEM

EXEN P RODUCT N O . 801578 & 801576)
1. Set Regulator to an air pressure high enough to
allow machine start-up without tripping and engage
Torque Limiter (See Fig. 7).
2. Start Machine.
NOTE: Torque Limiter must be engaged before starting
machine.
3. Set Regulator to an air pressure that will allow
machine operation, but low enough to allow Torque
Limiter disengagement in the event of a machine
overload (See Fig. 7).
4. If an overload occurs, the Torque Limiter Interface
separates, moving the cylinder to the outer position.
This movement is detected by the Proximity Sensor,
which de-energizes the 3-Way Solenoid Valve, thus
exhausting air from the Torque Limiter. Internal
springs provide assistance for a total, crisp, Torque
Limiter release (See Figure 7).

1. Set Regulator No. 1 to an air pressure high enough
to allow machine start-up without tripping of the
Torque Limiter (See Fig. 8).
2. Set Regulator No. 2 to an air pressure that will allow
machine operation, but low enough to allow Torque
Limiter disengagement in the event of a machine
overload (See Fig. 8).
3. Start machine.
NOTE: Torque Limiter must be engaged before starting
machine.
4. After a preset period of time, the Timer Delay
Control will de-energized the 3-Way In-line Mount
Solenoid Valve and allow only the lower running air
pressure set by Regulator No. 2 to the Torque
Limiter (See Fig. 8).
5. If an overload occurs, the Torque Limiter Interface
separates, moving the cylinder to the outer position.
This movement is detected by the 3-Way Air In-line
Mount Solenoid Valve, thus exhausting air from the
Torque Limiter. Internal springs provide assistance
for a total, crisp, Torque Limiter Release.
